Specification of Letters Patent.

Patented Oct. 9, 1906.

Application filed July 11, 1906. Serial No. 325,6 79.

To all whom it may concern.-

Be it known that I, ALBERT M. LORENTZ, a citizen of the United States ofAmerica, and a resident of McMechen, county of Marshall, and State ofWest Virginia, have invented certain new and useful Improvements inMilk-Strainers, of which the following is a specification.

My invention relates to new and useful improvementsin milk-strainers,and more particularly to a sanitary milk-strainer of that class in whicha 'cloth is used and it consists in the particular construction,arrangement, and combination of parts, which will hereinafter be fullydescribed.

The object of the invention is to provide a milk-strainer by means ofwhich the milk is freed from particles of foreign matter and .sedimentwhich is carried in suspension thereby.

A further object is to provide a milkstrainer the construction of whichis such that forei n matter or sediment contained by the milk isdirected from the meshes of the strainer to a point where it remainsduring the straining process and is prevented from dislilntegrating andpassing through with the m1 In describing the invention in detailreference is herein had to the accompanying drawing, forming a part ofthis specification, in which the figure is a vertical section of theinvention.

Referring to said drawing, 1 indicates a funnel-shaped receptacle, inthe lower end of which is secured a cylinder or casing 2. The upper endof said casing projects upward within said receptacle a short distanceabove the lower end of the receptacle, as shown.

Having its ends attached to the casing 2 at diametrically oppositepoints is a curved cross bar or wire 3 for supporting the strainer-cloth4 in a semi-oval position when the latter is secured in place over thetop of the casing by means of the clamping-ring 5. Said clamping-ring isprovided with a handle 6, by means of which it is readily applied andremoved.

As is obvious, milk poured into the receptacle 1 passes through themeshes of the strainer-cloth 4, which, being held by the wire 3, directsparticles of foreign substance or insoluble matter contained by the milkfrom its substantially convex upper surface to the annular V-shapedspace or channel 7,

bounded by the upper end of the casing and the lower end of the recetacle, where the objectionable matter is held. The particles of matterwhich lie in said annular space or channel 7 are not acted on by thecontinual flow of the milk, as is the case when permitted to lie uponthe surface of the strainer-cloth, and are therefore not subjected tothe disintegration consequent to continued pouring of the milk upon orover said particles.

In practice I prefer to employ one or more additional straining devicesin order toremove as nearly as practicable'all objectionable matter fromthe milk. In constructing a strainer to provide such. additionalstraining device a short cylinder or casing 8 is provided which has anannular horizontal flange 9 upon its lower end adapted for securing tothe lower end of the cylinder or casing 2, as shown. Said cylinder orcasing 8 is of less diameter than the casing 2, so as to form whensecured in place an annular space or channel 7*, into which particles offoreign matter which may have passed through the strainer-cloth 4 willbe directed by the curved surface of the strainer-cloth 4 Said cloth 4is held in place by a clamping-ring 5, having a handle 6"", and is heldin a position presenting a substantially convex upper surface by acurved cross bar or wire 3, as shown.

Obviously the strainer-cloth 4 must be secured in position prior tosecuring the cloth 4 in position, the said cloth 4 and clamping-ring 5being inserted from the top of the casing 2.

I have described the invention more or less in detail and in what Iconsider to be its simplest form; but it is obvious that various slightchanges may be made in the construction and arrangement of some of theparts without departing from the general spirit or scope of theinvention. Hence I do not wish to limit myself to the preciseconstruction and arrangement of parts herein shown and described.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In combination with a funnel-shaped receptacle, a casing secured tosaid receptacle and projecting thereinto forming an annular channel inconjunction therewith, an arcuate wire mounted upon said casing at itsupper end, a strainer-cloth mounted over said wires, and a clamping-ringfor securing ICC and projecting thereinto, a strainer of convex formcovering the inner end of said casing, a second casing within said firstcasing and spaced therefrom to form a channel in con junction therewith,and a strainer of convex form covering the inner end of said secondcasing. I

3.- In combination with a receptacle, a cast ing secured to thereceptacle and projecting thereinto, a second casing spaced from saidfirst-named one and having an annular horizontal flan e on its lower endsecured to said first-name casin to form a channel in conjunctiontherewit 1, arcuate wires secured to the upper ends of each of saidcasings, a strainer-cloth engaging .over each of said wires, and.clarnpingerings for securing said straining-cloths to said casings.

4. In combination with a funnel-shaped receptacle, a casing secured atan intermediate point along its length to the smaller end of saidreceptacle to form 'a channel in conjunction therewith, a convexstraining elementvcovering the inner end of said casmg, a

second casing within the first casing and spaced therefrom, a convexstraining element covering the inner end of said second casing, and.clamping-rings for securing said straining elements in place.

5. In combination with a funnel-shaped receptacle, a casing securedintermediate its ends in the lower end of said receptacle and having itsupperend projected upward within said receptacle, a second casing withinsaid firstcasing at its lower end and spaced therefrom to form a channelinconjunction therewith, arcuate wires secured to-the upper ends of saidcasings, and straining elements mounted over said wires, said strainingelements being supported by said wires and presenting convex upper facesadapted for directing insoluble matter therefrom.

Signed by me in the presence of two subscribing witnesses.
